IN CASE OF DIFFICULTY
If you are having trouble, or suspect a problem with your CV Series amplifier, try some simple troubleshooting before contacting an Authorized Carver Professional Dealer, Authorized Carver Professional Service Center or Carver Professional Technical Service. Below are listed some general problems and items that should be checked in an attempt to resolve the difficulty.
No Sound, No Power
This is usually an indication of a power supply problem in either the power line itself or the amplifier’s power supply. Check the following:
1)CV Series amplifier’s power is switched off.
2)Line cord is disconnected.
3)Poor fit between the plug and AC receptacle.
4)Power off at AC receptacle (check with tester or lamp).
5)The amplifier is plugged into a switched outlet. Verify that the outlet is live.
6)CV Series amplifier’s fuse has blown. This amplifier contains no user serviceable fuses.
7)The thermal breaker in the power transformer has opened. Allow amplifier to cool and the breaker will
reset itself.
Power On, Low Output or No Output
Low or no output problems are usually
1)The input level controls are set too low.
2)Move the input connection to another amplifier that you know is working to verify that it is not a source problem.
3)Check speaker connections. Be sure that there are no small strands of wire touching similar strands coming from the other wire in the cable.
4)Make sure the speakers are functioning correctly.
5)If you are using
6)Use a voltmeter to determine if the power line voltage is dropping excessively when the amplifier is driven
hard.
Playback Is Mixed with Hum
1)Check or replace the connecting cables, between source and amplifier’s input.
2)Make sure that each screw terminal connection is tight.
3)Signal cables may have been routed too closely to the AC cables, power transformers, motors or EMI inducing device.
4)Try connecting another source to the power amplifier inputs. If the hum stops, the problem lies with the original source component.
